No one should be forced to use a facility they don't feel comfortable using. Otherwise people end up being excluded. /1

Some women don't feel comfortable or safe sharing facilities with the opposite sex. They must not be forced to. They need to be able to choose a female-only option instead /2

Some trans people don't feel comfortable or safe sharing facilities designated for their birth sex. They must not be forced to. They need to be able to choose a mix-sex option instead /3

This is fully inclusive set of options. Something for everyone. No one is excluded. /4

Great thing is these facilities already exist. There is an excellent network of accessible facilities – set up originally for wheel chair users – but their purpose is now much wider. They are available to anyone who needs an accessible alternative. /5

Mixed-sex accessible facilities already exist to make not one is excluded. People with hidden disabilities, people with buggies, people who needed to be accompanied by the opposite sex carer or parent, people who want to keep their birth sex private. /6

No one ever needs to be forced to use a facility they don't want. That includes not forcing women and girls too. /7

If males are included in female-only facilities they are no longer female-only.

If a woman chooses female-only she is not consenting to share with males. /8
